Quantum Temporal Superposition: The Case of Quantum Field Theory
Quantum Temporal Superposition: The Case of Quantum Field Theory
Quantum field theory is completely characterized by the field correlations between spacetime points. In turn, some of these can be accessed by locally coupling to the field simple quantum systems, a.k.a. particle detectors. In this work, we consider what happens when a quantum-controlled superposition of detectors at different space-time points …
